In the alternate worlds of last night's "Lost" finale, the characters gather for the funeral of Jack's father in Los Angeles (above) even as Jack awakens on the island.

So, was it all smoke and no mirrors? Were you lost and now you’re found? Or are you still as confused as you were at the middle of Season Three?

The ever confusing, usually fascinating “Lost” — arguably the only show where quantum physics is as big a deal as the fabulous shirtless men — ended last night.

Since in the wacky world of quantum physics time is not linear but round, the dead characters were, it turned out, very much alive and reconnecting in the alternate world of Los Angeles — which, as we know, really is an alternate universe anyway. Or so it seemed.

The finale proved once and for all that “Lost” is the only series that could produce the ultimate reunion show by legitimately using flashbacks without ever having flashes in the first place.

That was a great technique for the reconnected lovers. Kate hooked up with Jack, who is married in the alternate world to Juliet; Sawyer mooned over Juliet, who is married to Jack in the other universe; and Claire (who, poor thing, has had to repeat labor and birth more often than Kate Gosselin) reconnected with her long-lost love, Charlie, the heroin addict.

And Hurley? He reconnected with his great love, Big Macs, and Locke reconnected with his legs — in both universes.

Meantime, the pilot got the crashed plane working while the island was shaking and combusting, and Kate, Claire, Miles, Sawyer and Richard escaped.

Back on the island, we had the ultimate showdown between Jack and the badly reincarnated Locke, whose body had been taken over by the scary Man-in-Black/Smoke Monster, who had vowed to destroy the island.

Advice: Don’t screw around with the Smoke Monster (unless you’re Kate, who pulled an Angelina Jolie and killed Locke last night.) All others, run like your ass is on fire!

While the remainder of the islanders escaped on the plane, Hurley and Ben refused to leave Jack behind and became co-savers of the island.

While Jack was fighting for his life on the island, he was getting sweaty over Kate at his father’s funeral. Jack’s dead father, Christian, told Jack in the roomful of everyone who had ever been on the island (and on the show), “This is the place you all made together so you can find one another. You’re not leaving, you’re moving on.” What? Were they all dead all along? Probably.

After the show was over, as the credits rolled, we saw the horrific, original wreckage.

Perhaps the series was really about what would or could or may have happened had they lived. The possibilities, the loves not loved.

So, no, my friends, there was no polar bear; Hurley wasn’t really able to stay fat despite a diet of mangos; and no one fell in love. Or maybe they did.

Who even knows if it’s really the end of the show.

Perhaps, like the plot itself, “Lost” is actually still playing somewhere in the alternate universe.
